Dear all,
I'm trying to collect ASCII-based progress information regarding a set
of performance counters. "Progress" means, for example, the ratios of
values/second (e.g. page faults/seconds).
I can get information in this form using 'perf stat' but 'stat' only
gives me the final value. I would like to collect, or calculate,
theses values from the running command and determine how these metrics
evolved over time (i.e. faster or slower).
Is this possible (or eventually trivial) with the perf tool?
Thank you,
José

Newer perf stat has a -I (interval) option for this.

Thank you for your answer.
How can I get more information regarding the update of my system to
use this new version of perf?
